MOTOR-VEHICLE SPECIFICATION forming part of Letters Patent No. 688,838, dated December 17, 1901.

' Application filed March 19,1901. Serial No. 51,838. (No modcl To a/ZZ whom, t may concern:

Be it known that I, FARNUM FRANCIS DORSEY, of Winchester', in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvementin Motor-Vehicles, of which the following is a specification, reference being had to the accompanying drawings, in which Figure l is a side elevation of my new m0- tor-vehicle. Fig. 2 is a side elevation of the motor. Fig. 3 is a plan view of the motor, the fuel-tank being removed and one-half being shown in section on line AA, Fig. 2. Fig. 4c is a detail showing a locking device secured to the handle-bar.

My invention relates to motor-vehicles, and has for one of its objects to provide driving means free from clutch mechanism and transmission-gearing-that is, to produce a directconnected motor-vehicle. The iiy-wheel is brought into and out of direct frictional contact with the rear wheel of themotor-vehicle, and the use of clutch mechanism and gearing is obviated thereby.

Another object of my invention is to provide simple means for controlling the power applied. By mechanism hereinafter described the fly-wheel of the motor is raised out of contact with the rear wheel of the motor-vehicle, and simultaneously the flow of the fuel and lubricant is stopped and the igniting battery-circuit is opened. Also the ow of the fuel and lubricant is made to vary directly with the degree of friction or pressure between the fly-wheel of the motor and the wheel of the motor-vehicle.

A third object of my invention is to adapt a two-cylinder engine to a motor-vehicle. By using a two-cylinder engine a more perfect balance is obtained and a more uniform thrust upon the main shaft of the motor. Again, greater power for the same weight is obtained, and the power applied may be made to vary from a light load on one cylinder to a heavy load on both cylinders.

A fourth object of my invention is to dis-fV pense with unnecessary valves and in other ways to simplify the construction. Infthe motor hereinafter described the functions of vaporizervalve, inlet valve, and.Y throttlevalve are performed bya single valve. VThe functions of iywheel and friction driverare journaled in the frame at 2, Fig. l.

Wheel are performed by one Wheel-the iiyi wheel of the motor. The fuel-tank incloses the lubricant-tank. The cylinders are screwed into the crank-cases and secured by a locking-nut.

Another object of my invention is to provide a simple means for locking the motor and its supply mechanisms in any desired position.

My invention consists in the mechanisms and combination of mechanisms hereinafter described and claimed.

In the drawings illustrating the principle of my invention and the best mode in which I have contemplated applying that principle, ais the frame of the motor-vehicle, b 'the front wheel, and c the rear wheel. The motor is a double-cylinder motor having a shaft d, upon which is the fly-wheel e. The cylindersfaro screwed into the crank-cases g and are locked therein by means of the nuts h. The pistons z' are, by means of the connecting-rods,y and wrist-pins 7o, secu red to the cranks Z, fast upon shaft CZ. The fly-wheel e is centrally located between the crank-cases g, and above it is secured to the motor-frame the fuel-tank m, Figs. 1 and 2. The fuel is supplied to the valve-casing through the pipe n, and the supply is controlled by the valve o. The lubricant is held in a cup p, inclosed in the fueltank fm, and is fed by capillary attraction into the pipe 1'. The iiow of the lubricant is controlled by the valve s, provided with a crankarm t. From the poles of the battery u, Fig. l, extend wires, one to a circuit-breaker (not shown) and thence to the binding-posto and the other to one terminal of the primary of the Ruhmkorlf sparkcoil w, Fig. l. The binding-post o is separated by the insulation oo, Fig. 3, from the crank-casing. The common terminal of the primary and secondary is connected to the frame ot the motor-vehicle, as at y, Fig. l, and the other terminal is COUDected to the igniter e'.

rThe motor is supported by trunnions, wlliilph is construction permits the motor to be lowered and raised on its trunnions to bring the iiywheel into and out of contact with the rear wheel c of the motor-vehicle. Secured in the front end of the frame ofthe motor is a pin 3, Fig. 3, the ends of which are pivotally secured in the crank-arms 4, one of which is Y cont-act until just before the spring 11 reachesV shown in Fig. 1. The crank-arm 5 is joined by a link 6, Figs. 1 and 2, to a lever 7, the upper end of which is connected by a link 8 to the crank-arm t, that turns the Valve 8, which controls the supply of lubricant. To the lever 7 is secured a wedge 9, Fig. 3, that is adapted to engage a wedge 10, secured to the fiat spring 11. The engagement of the wedges 9 and 10 is produced by the forward lnovement of the lever 7 and results in breaking the battery-circuit, as willbe evident from Figs. 1 and 3. Again, when the spring 11 is raised it engages ille head 12 of the valvestem 13 and draws the valve 14 tightly against the valve-seat 15, Figs. 2 and 3. Thus the forward movement of the lever 7 breaks the battery-circuit and shuts off the fuel-supply from the cylinders. The crank-arm 16, Fig. 1, is joined by the link 17 to one arm of the bell-crank 18, lthe other arm of which is connected bythe link 19 to the lever 20. A lug 2l, formed on the lever 20, is adapted to engage the teeth of the rack 22, that is formed on the wall of the slot in the swinging arm 23. The crank-plate 24, Fig. 1, from which project the crank-arms 16, 4, and 5, is fast upon the shaft 25, upon thev other end of which is fastasimilarcrank-plate. (Not shown.) A spring 26 connects the crank-plate 24 to the frame a of the motor-vehicle.

The operation of my motor-vehicle is as follows: The lug 2l on the lever 20 is disengaged from the teeth 22 and the rear end of lever 2O is raised, by which, iirst, the motor flywheel e is lowered into contact with the rear wheel c of the motor-vehicle; second, the valve 8 that controls the flow of lubricant is opened, and, third, the wedges 9 and 10 are disof the motor is decreased by pushing the swingingarm 23 forward, releasing the lever ,20, and lowering the rear end of the lever 20.

This movement of lever 2O is transmitted by the link 19, bell-crank levell 18, link 17, crankplate 24, crank-arm 5, and link 6 to lever 7. The forward movement of lever 7 causes the 'wedge 9 thereon to engage the wedge 10 on the spring 11, and thereby raise the spring 11. This raising of the spring 11 limits the throw'of thevvalve 14,'"so as to decrease the amount of air and fuel drawn in`,'orthe supply is throttled.7 As the spring 11 is raised the spring q follows it, so as to preserve the the limit of its motion. When the spring 11 has reached the limit of its motion, the battery-circuit is opened and the valve 14 is locked tightly on its seat. Y (See dotted lines, Fig. 3.) By the same operation the valve 8 has through the crank t and the link 8 been closed, so as to shut off the flow of the lubricant. By the same operation the fly-wheel e is raised out of contact with the tire of the rear wheel c. The speed of the motor is increased by reversing the operation--that is, raising the rear end of the lever 20. The desired speed having been obtained, the lever 2O is locked in position by the engagement of the lug 21 with the teeth 22.

In my new motor-vehicle the supporting pivotal points or trunnions of the motor are between its ends and near the junction of the crank-cases and the cylinders, and hence near its center of gravity. This reduces the force necessary to raise the motor and makes easier the operation of the controlling devices. 1
